I can get mine to sit at 4300+ with 1.52+v for benchmarks (3Dmark11,heaven etc) but that about it.... whats the point really?
Crysis2, my 955BE bsod @ 4.2 but BF3 will play without a worry.
If i was you i'd be happy with 4.2. I'd also get those volts down below 1.55 if i could.
What's wrong with ya PII. Why change?
